four wheel drive Alfa Romeo MiTo 2016 Owner's Manual

ESC (Electronic Stability
Control) SYSTEM
This is an electronic system that controls vehicle stability in the event of
tyre grip loss, helping maintain directional control.
The system is capable of recognising potentially dangerous situations
in terms of the stability and intervenes automatically on the brakes in a
differentiated manner for the four wheels in order to provide a
stabilising torque.
The ESC system also includes the following systems:
❒Hill Holder
❒ASR
❒Brake Assist
❒MSR
❒CBC
❒“ELECTRONIC Q2” (“E-Q2”)
❒DST
SYSTEM ACTIVATION
The ESC system switches on automatically when the engine is started
and cannot be switched off.
SYSTEM INTERVENTION
It is signalled by the blinking of the warning lighton the instrument
panel, to inform the driver that the car is in critical stability and grip
conditions.
HILL HOLDER SYSTEM
This system is an integral part of the ESC system and facilitates starting
on slopes.
It is automatically activated in the following conditions:
❒uphill: vehicle stationary on a road with a gradient higher than 5%,
engine running, brake pedal pressed and gearbox in neutral or
gear (other than reverse) engaged;
❒downhill: vehicle stationary on a road with a gradient higher than
5%, engine running, brake pedal pressed and reverse gear
engaged.
When setting off the ESC system control unit maintains the braking
pressure at the wheels until the engine torque required for departure is
reached or for approximately 2 seconds, allowing your right foot to
be moved easily from the brake pedal to the accelerator.
If the vehicle has not departed after this time, the system will deactivate
automatically by gradually releasing the brake force. A sound may
be heard during this stage: this indicates that the vehicle is about
to move off.
IMPORTANT The Hill Holder system is not a handbrake. Do not leave
the vehicle without having engaged the handbrake, switched off the
engine and engaged a gear.

ASR (AntiSlip Regulation) SYSTEM
It is an integral part of the ESC system. It automatically operates in the
event of one or both drive wheels slipping, loss of grip on wet roads
(aquaplaning) and acceleration on slippery, snowy or icy roads, etc.
Depending on the slipping conditions, two different control systems are
activated:
❒if the slipping involves both drive wheels, the ASR intervenes
reducing the power transmitted by the engine;
❒if the slipping only involves one of the drive wheels, the ASR
intervenes automatically braking the wheel that is slipping.
For the ESC and ASR systems to function correctly, all
four tyres must be the same brand and type, must
be in excellent condition and, above all, must be of the
prescribed type and size.
The ESC system operates even when the space-saver
wheel is being used. Always remember that the
space-saver wheel, being smaller than the original
wheel, provides less grip.
The performance of the ESC and ASR systems must not
encourage the driver to take unnecessary risks. Driving
style must always be adapted to road conditions,
visibility and traffic. The driver is, in any case, responsible for
safe driving.
BRAKE ASSIST (emergency braking
assistance)
The system, which cannot be turned off, recognises emergency braking
(on the basis of the brake pedal operating speed) and speeding up
the response of the braking system. The Brake Assist device is
deactivated if there is a ESC system failure.
MSR (Motor Schleppmoment
Regelung) SYSTEM
This system is an integral part of the ABS, that intervenes, if there is a
sudden downshifting, restoring torque to the engine, thereby
preventing excessive drive at the drive wheels which, especially in poor
grip conditions, could lead to a loss in stability of the car.
CBC (Cornering Brake Control)
SYSTEM
This function improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking on bends if the ABS intervenes. This improves stopping
distances and above all vehicle stability when cornering.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an effect
similar to a limited slip differential.
The front braking system, when accelerating around a curve, acts on
the inside wheel to increase the drive to the outside wheel (increased
load), dynamically and continuously distributing the torque between
the front drive wheels according to driving and road conditions.
The system, combined with MacPherson front suspension, allows
particularly effective and sports driving to be achieved.

INSTALLING A TOW HOOK
Contact Alfa Romeo Authorised Services to install a tow hook.
The ABS with which the car is equipped will not control
the braking system of the trailer. Particular caution is
therefore required on slippery roads.
Do not, under any circumstances, modify the vehicle's
braking system to control the trailer breaking system.
The towing breaking system must be completely
independent of the vehicle's hydraulic system.
SNOW TYRES
Use snow tyres of the same size as the normal tyres provided with the
car: Alfa Romeo Authorized Services will be able to advise you on
the most appropriate tyre to use.
Only use these tyres in the event of ice or snow on the roads.
For the type of snow tyre to be used, inflation pressures and the
specifications, strictly follow the instructions given in the "Wheels"
paragraph in the "Technical specifications" section.
The winter performance of these tyres is considerably reduced when
the tread thickness is less than 4 mm. Replace them in this case.
Due to their specific features, the performance of snow tyres is much
lower than that of normal types in normal conditions or long motorway
stretches. Their usage should therefore be restricted in accordance
with their type approval.
All four tyres should be the same (brand and track) to ensure greater
safety when driving and braking and good driveability. Remember
that it is inadvisable to change the rotation direction of tyres.
The maximum speed for snow tyres marked “Q” is
160 km/h, while it is 190 km/h for “T” tyres and 210
km/h for "H" tyres. The highway code speed limits
must however always be complied with.
